Middle East War Doubles Shipping Fuel Prices: Strait of Hormuz Blockade Impact

San Francisco, CA – Ship fuel prices are soaring to levels unseen in years, driven by escalating tensions in the Middle East and disruptions to vital shipping lanes. The cost of very low sulphur fuel oil (VLSFO), a common fuel source for many vessels, has nearly doubled since late February, placing significant strain on global trade and raising concerns about further economic fallout. The crisis centers around the Strait of Hormuz, a critical chokepoint for global oil and gas transport, where disruptions are impacting the supply of ship fuels to ports throughout the region.

The surge in bunker fuel costs – the term for fuel supplied to ships – is not merely an isolated issue for shipping companies. It’s a harbinger of broader inflationary pressures, as carriers are already implementing emergency surcharges to offset the increased expenses. This will inevitably translate to higher costs for consumers across a wide range of goods, from manufactured products to energy supplies. The situation is particularly acute for nations heavily reliant on maritime trade, and the potential for widespread economic disruption is growing with each passing day.

The current crisis stems from the ongoing conflict in the Middle East, which has led to increased instability and, crucially, restrictions on passage through the Strait of Hormuz. Even as the exact nature of these restrictions varies, reports indicate a significant slowdown in traffic, with over 1,000 cargo ships, primarily oil and gas tankers, blocked from transiting the strait since the conflict began on February 28th. This blockade has severely limited the availability of ship fuels in the region, driving up prices dramatically. The situation is further complicated by attacks on vessels in the area, including an incident at Fujairah port in the United Arab Emirates over the weekend and Monday, as reported by industry journal Ship and Bunker.

The Price Shock: A Dramatic Increase in Bunker Fuel Costs

Data from industry monitor Ship and Bunker reveals the extent of the price increases. The average price of VLSFO across the world’s 20 largest refuelling ports reached $1,017 per tonne on Wednesday, March 18, 2026 – a staggering increase from $544 per tonne on February 27th. This represents a nearly 87% increase in just over three weeks. The price surge is comparable to levels not seen since the Russian invasion of Ukraine, according to researchers at HSBC bank. In Singapore, the world’s largest bunkering hub, VLSFO prices have risen by 106 percent during the same period. Even ports further removed from the immediate conflict zone are experiencing increased demand and rising prices.

Constantinos Capetanakis, chairman of the International Bunker Industry Association (IBIA), emphasized the urgency of the situation. “These are urgent situations and circumstances. You need to plan ahead as much as possible,” Capetanakis told AFP, calling for “calmness and realism” from the shipping industry. He likewise noted that bunker costs typically account for approximately 50% of a ship’s total operating expenses, highlighting the significant financial impact of these price hikes.

Strait of Hormuz: A Critical Chokepoint Under Pressure

The Strait of Hormuz is a narrow waterway separating Iran and Oman, connecting the Persian Gulf with the Gulf of Oman and the Arabian Sea. It’s a vital artery for global energy supplies, facilitating the transport of roughly one-fifth of the world’s crude oil. At its narrowest point, the strait is just 21 nautical miles wide, making it vulnerable to disruption. Historically, the strait has been a target for leverage during times of regional conflict, most notably during the Iran-Iraq “tanker war” in the 1980s, prompting the U.S. Navy to initiate Operation Earnest Will in 1987 to ensure safe passage.

The current situation echoes those past concerns. The closure, or even significant restriction, of the Strait of Hormuz has the potential to trigger a major global economic crisis. Beyond oil, the strait is a crucial transit route for liquefied natural gas (LNG) and other essential commodities. The disruption to shipping traffic is already impacting supply chains and driving up transportation costs, with ripple effects felt across numerous industries. According to The Guardian, most shipping traffic through the strait has been halted since early March, with approximately 20 vessels reportedly attacked in the area.

Industry Responses and International Efforts

Shipping companies and freight firms are adapting to the escalating fuel costs in several ways. Reports indicate that many are ordering ships to leisurely down – a practice known as “slow steaming” – to reduce fuel consumption. Others are exploring alternative routes and ports to bunker, adding time and expense to their voyages. These adjustments, while mitigating some of the immediate financial impact, are also contributing to longer delivery times and potential supply chain bottlenecks.

The international community is grappling with how to address the crisis. The UN International Maritime Organization (IMO) began two days of talks on Wednesday, March 18th, to discuss efforts to ease the shipping crisis. However, finding a consensus on a coordinated response is proving challenging. According to The Guardian, officials from the Trump administration have suggested forming an international naval taskforce to reopen the strait, but enthusiasm for such a proposal remains low, with many countries hesitant to become directly involved in the conflict.

US Military Intervention and Bunker Buster Bombs

On Tuesday, March 17, 2026, U.S. Forces conducted strikes against Iranian anti-ship missile sites near the Strait of Hormuz, utilizing 5,000-pound bunker buster bombs. U.S. Central Command (CENTCOM) stated that the strikes targeted sites posing a risk to international shipping. These deep penetrator munitions, designated GBU-72, are designed to destroy hardened or underground targets. Fox News reported that the munition was first tested by the Air Force in 2021. The bombing raid comes after Iran closed off the strategic waterway, through which approximately one-fifth of the world’s oil flows, in retaliation for the war initiated by the United States and Israel.

While the U.S. Military action aims to deter further attacks on shipping, it also carries the risk of escalating the conflict. The effectiveness of the strikes in restoring safe passage through the Strait of Hormuz remains to be seen. The cost of each GBU-72 bomb is estimated at $288,000, according to an Air Force Times report from 2022, though these are less powerful than the 30,000-pound bombs used in previous operations against Iranian nuclear sites last year.

Looking Ahead: Uncertainty and Potential for Further Disruption

The situation in the Strait of Hormuz remains highly volatile and unpredictable. The ongoing conflict, coupled with the potential for further disruptions to shipping traffic, suggests that high bunker fuel prices are likely to persist in the near term. The IMO talks represent a crucial opportunity to forge a coordinated international response, but the path forward remains uncertain. The next key development to watch will be the outcome of the IMO discussions and any further statements from major maritime powers regarding their plans to ensure the safe passage of vessels through the strait.

The global shipping industry, and the world economy as a whole, are bracing for a prolonged period of uncertainty. Continued monitoring of the situation and proactive planning will be essential for mitigating the risks and navigating the challenges ahead.
